Is a 96% battery health normal for an iPhone 15 Pro?
I bought an iPhone 15 Pro in October 2024, and its battery health was perfect until February. In February, it decreased by 1 percent, but suddenly, in March, it dropped to 69% within a week. I always maintained a charging range of 20–80 percent. Can anyone tell me why this is happening?
